WebAug 23, 2024 · Cysteine proteases. Cysteine proteases (also known as thiol proteases) catalyze the breakdown of proteins by cleaving peptide bonds using a nucleophilic thiol from a cysteine (Figure 4.63). The cysteine is typically found in a catalytic dyad or triad also involving histidine and (sometimes) aspartic acid (very much like serine proteases).
WebJan 20, 2024 · For our review of the mechanisms of inhibition of cysteine proteases, we selected crystal structures of diverse types of inhibitors, which either target large groups of related proteases, such as papain-like proteases and caspases, or others including calpastatin and securin, with unique mechanism(s) of inhibition.
